- -UNIVTED STATES PATENT OF ICE-g PI RR JEAN RENE Pos'rEL-vmAY, 0FPARIS, FRANCE, AssIGNoE. 'ro SOCIETE DES MoT Uns SALMSON(sYsTEME-cANToN-UNNE),or BILLANCOURT, ERA-Non To all whom it mayconcern:

planes, designed for connecting together a longitudinal, a fuselagestrut, a cabin.stanchion, a wing longeron and a corresponding strut ofthe landing carriage.

The improved junction piece has the form of a box; it is also providedwith lugs for the attachment of the stay wires. It provides a strongmeans of connection that can be fixed very simply. By its attachment tothe landing carriage struts it enables the strains due to landing to betaken by the same parts that take the strains due to flying.

The accompanying drawings illustrate by way of example a constructionalform of this invention.

Figure 1 is a diagrammatic side elevation of an aeroplane showing thelocation of two improved junction pieces.

Fig. 2 is a partial front end elevation of a landing carriage, showingthe connections made by means of the two improved junc tion pieces. r

. Figs. 3, at and 5 are respectively an end elevation, a section on theline AA of Fig. 3, and a plan of an improved junction piece.

Figs. 6 and 7 are two perspective views of the improved junction piecetaken from two opposite ends of the same. In these two views it isassumed that only a'fuselage longitudinal and a cabin stanchion aremounted in position.

It will be perceived fromFigs. l and 2 that the junction pieces a arearranged at the junction ofthe landing carriage struts Z), the fuselagelongitudinals 0 and the cabin stanchions at. These junction piecesreceive also the fuselage struts e and the wing. longerons f.

They are also formed with lugs forythe attachment of thelandingfcarriage stay wires 9 and the cell stay wires it. e v i Theimprovedjunction piece or fitting comprises a central forged steelsleeve 0 which is carefully bored'to the desired diameter sojthat thetransverse strut e of the fuselage may be adjusted and riveted thereinas shown at 0 (Fig. 4:), the riveting taking place however only afterthe whole junction piece has been constructed. To the central sleeve 0are welded two lower vertical side pieces p 19 and two horizontal strutplates to a extending between the side members 19 12 so as to form ahorizontal channel open at its bottom face, in which the fuselagelongitudinal 0 is received. The side plates. 7

p p are provided with holes 2' through The strap is hasa lug Z for theattachmentv of the stay wires 9. The inner wall 29 of. the junctionpiece has lugs m and a for the attachment of other stay wires. To theouter end of the central sleeve 0, is welded a ring plate or flange 9provided with two vertical lugs 9 between which the wing longeron f isinserted.

A metal plate r is placed around the sleeve 0 between the side plate pand the flange q and welded to the parts 0 and p; the upper part of saidplate is turned over so as to form a lug 1 which serves for theattachment of the cell stay wires h.

The cabin stanchion d is fitted into a rectangular socket 8 formed of ametal plate suitably bent and welded. Said socket is welded at its lowerend upon the central sleeve 0. The cabin stanchion d is secured in saidsocket by means of a bolt 25 extending through two oppositelugs sintegral with the socket.

The junction piece is lightened by the provision of recesses in itswalls as shown.

l. A junction piece for aeroplane mem-' bers comprising a central sleevepart in' which a cross member of the fuselage is adapted to'be riveted,opposite lower vertical plates and horizontal truss plates welded tosaid sleeve and forming a channel adapted to receive a fuselagelongitudinal, means landing carriage and adapted tobe secured to saidlower vertical pl'ates,bolts extending through said plates and thefuselage longitudinal, a' socket member for a vertical stanchion weldedupon the said central sleeve and alug carrying plate welded to the endofthe central sleeve and adapted to receive a wing beam.

2.-A junction piece for aeroplane members comprising a central sleevepart, in

which a cross member of the fuselage is adapted to be riveted,'oppositelower ver tical plates and horizontal truss '1 plates welded to saidsleeve and forming a channel adapted to receive a fuselage longitu-.dinal,'-means=carried by the corresponding strutof the landing carriageandvad'apted to bolts ektending through said plates andthe to the end ofthe central sleeve andadapted to receiveafwing longitudinal, .a plateinserted between said flange on one side and one of the lower verticalplates and .the socket 'member'on the other'side, about the centralsleeve, said platebeing welded tothe adjacent parts and a lug madeintegral with said plate for the attachment of stay wires.

In testimony whereof I have signed my name to this specification.
